What Type Of Rock Is Peridotite?
Is peridotite sedimentary or metamorphic?
What is the metamorphic rock of peridotite?
Peridotite is the general name for the ultrabasic or ultramafic intrusive rocks dark green to black in color dense and coarse-grained texture often as layered igneous complex. From: Introduction to Mineralogy and Petrology 2014.
What type of igneous rock is peridotite and Dunites?
Is peridotite a mafic rock?
Is peridotite an igneous rock?
peridotite a coarse-grained dark-coloured heavy intrusive igneous rock that contains at least 10 percent olivine other iron- and magnesia-rich minerals (generally pyroxenes) and not more than 10 percent feldspar.
What type of rock is phyllite?
|Composition||Muscovite Biotite Quartz Plagioclase|
Is peridotite an andesitic?
|Secondary||Magnetites biotite sphene and quartz|
What type of rock is basalt?
Basalt is a hard black volcanic rock. Basalt is the most common rock type in the Earth’s crust. Depending on how it is erupted basalt can be hard and massive (Figure 1) or crumbly and full of bubbles (Figure 2).
What is peridotite quizlet?
peridotite. A coarse-grained ultramafic intrusive igneous rock composed of olivine with small amounts of pyroxene and amphibole. The dominant rock in Earth’s mantle and the source rock of basaltic melts.
Why peridotite is densest among igneous rocks?
The crystals are heavier than the melt and sink to the bottom of the melt. These high-temperature minerals can form layers of peridotite on the bottom of the magma body.
Is dunite and peridotite?
Why is peridotite so dense?
Peridotite is a dense coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene. Peridotite is ultramafic and ultrabasic as the rock contains less than 45% silica. It is high in magnesium reflecting the high proportions of magnesium-rich olivine with appreciable iron.
Is peridotite same as peridot?
As nouns the difference between peridotite and peridot
is that peridotite is (geology|mineralogy) a rock consisting of small crystals of olivine pyroxene and hornblende the major constituent of the earth’s mantle while peridot is a transparent olive-green form of olivine used as a gem.
How is basalt formed?
What is the density of peridotite?
What type of rock is gneiss?
gneiss metamorphic rock that has a distinct banding which is apparent in hand specimen or on a microscopic scale. Gneiss usually is distinguished from schist by its foliation and schistosity gneiss displays a well-developed foliation and a poorly developed schistosity and cleavage.
What texture is basalt?
|Color||Dark Gray to Black|
Is peridotite plutonic or volcanic?
What type of foliation is phyllite?
What kind of foliation does phyllite have?
Is phyllite contact or regional?

What is basalt porphyry?
What is the difference between basalt and andesite?
Both lavas are formed at different plate boundaries which is why they have different silica contents: the basaltic lava forms from the hot mantle material at constructive plate boundaries and hotspots whereas the andesitic lava forms at destructive plate boundaries from melting crust.
How does basalt turn into andesite?
Is basalt a sedimentary rock?
Is basalt metamorphic rock?
Is basalt sedimentary igneous or metamorphic?
What is basalt astronomy quizlet?
Basalt a dense congealed lava rock rich in iron is the primary material in the Moon’s. Maria. One result of bombardment on the Moon’s surface is a layer of broken pulverized and powered rock called. Regolith.
What type of rock is granite quizlet?
Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth’s surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals.
What kind of magma is made from the partial melting of mantle peridotite?
most basaltic magma originates from partial melting of ultramafic rock (peridotite).
What is the specific gravity of peridotite?
5. Peridotite is a compact dark greenish rock with a specific gravity of 2.781.
What is the grain size of peridotite?
F-type peridotites are fine-grained (olivine ∼60–70 µm across).
Is basalt a plutonic rock?
